Principle
The gas detector uses a pump-suction Sampling method with a built-in powerful air pump to suck the gas to be tested into the inside of the instrument. The gas is contacted by the built-in import electrochemistry or infrared absorption gas sensor through a reasonably designed gas chamber. The sensor converts the gas concentration signal into an electrical signal, which is processed and analyzed by a microcontroller and a 24-bit ADC data collection chip for High Accuracy, and finally displays the concentration value in real time on the screen. The instrument has a temperature compensation function to reduce the impact of environment temperature on the measurement results.
